MILK-COOLER.

SPECIFICATION forming part of Letters Patentv No. 248,123, dated October 11, 1881.

Application led July 11,1881. (No model.)

To all whom it may concern Be it known that I, IRA C. WIGHTMAN, of Severn Valley, in the county of York, in the State of Pennsylvania, have invented animprovementin Milk0oolers, of which the following is a specification.

My invention relates to milk-coolers; and it consists in a water-tight box or tank in which is hung a metal vat, said vat being provided 1o with flattened tubes open wholly at one end, but only at the top at the other end; further, in providing the vat with a cream-glass and means for securing said vat to the wooden tank or box, whereby said glass is exposed through an opening in the wooden tank, but the joint about said openingis made perfectly water-tight; further, in providing an ice-box at one end, in combination with tubes for feeding and discharging the cold water, and a zo pump to keep up the circulation of same, all

of which is more fully set forth in the following specification, and shown in the accompa nying drawings, which form part thereof.

The object of this invention is to provide aV 2 5 cream-inspecting glass to the vat in a coolerV of this construction, so that the cream can be clearly seen without looking through a body of water, and to cause a more perfect circulation of the cold water through and around tbe 3o milk in the vat.

In the drawings, Figure l is a sectional plan of In Y improved milk-cooler on line y y. Fig. 2 is a sectional elevation of same on line zz. Fig. 3 is a cross-section of same online a' x. D is the tank or Water and ice box, and is provided at one end with a vertical slot, L

Suspended in the tank D is the cream and milk vat A, which is provided with attened tubes B, extending from one end to the other, 4o and just clear ofthe bottom. One end of the tubes B is entirely open, and the other end is closed, and into the upper end of which theV feed-pipes C enter. One end of this vat A is provided with a cream-glass, F, and said vat 4 5 is bolted or otherwise secured to said tank D,

as shown in Fig. l. To eiect this the creamglass F in the vat A is brought to register with the slot cl of the tank D,vaud a packing, Gr, is arrangedl between said vat and tank and 5o about said slot d and cream-glass F,'and they are then clamped together by bolts g, thereby leaving a space between the vat and tank for the circulation of the water. The tank is longer than the vat, and the space between the two is used as an ice-box. i

H are the discharge-pipes, arranged at different levels, and are provided with valves h. These discharge-pipes H connect with the suction-port of a water-pump, J, andthe discharge-port of same is connected with the 6o feed-pipes C.

A tap or valve, I, opens from the vat A at the bottom and passes through the'tank D, in which itis made water-tight.

The operation is as follows: Milk being placed in the vat A and Water and ice in the tank D, the pumpuJ is operated. The water in a cold condition is sucked fromthe tank b v pipes H and forced into the pipes C, and thence into the top of the flattened tubes B, 7o and is then discharged at the otherend, Where part passes between the vat and tank and passes back to its starting place after having passed between the sides and bottoms of the `with pipes C, to admit water into the other end, which is closed, substantially as and for the purpose specified.

2. In a milk-cooler, the tank D,in combination with the vat A, provided with tubes B, 9o extending horizontally and entirely across the yat, said tubes being closed at one end, into which water is fed at the top by pipes C, and are open at the other-end, substantially as and for the purpose specified.

3. In a milk-cooler, the tank D, provided with slot or aperture d, in combination Witha vat, A, provided with a cream-glass, F, and -tubes B, extending horizontally and entirely tank and vat,thereby coolin gthe milk perfectly. 75

across the vat, said tubes being closed at one roo end, into which cold water is fed at thetop by pipes G, and are open at the other end, and a packing, G, to make the opening or slot d in tank D to the cream-glass Water-tight, substantially as and for the purpose specified.

4. In a milkcooler, the tank D, provided with the opening or slot d, and the vat A, pro vided with the cream-glass F, in combination with a packing, G, between saidtank and vat and around the creamglass, `and horizontal tubes B, arranged on either side of the creamglass and opening into theend of thevat,sub stantially as and for the purpose specified.

5. In a milk-cooler, the combination, with the tank D, provided with discharge-pipes H In testimony of which invention I hereunto 25 set my hand.
